1 By: The Robotic Pandas

2 What community did we research?  Avon, CT  Avon is a suburb of Hartford  Population is 17,209  Our town, Avon, consists of beautiful parks, a river, forests, and it is a great school district.

3 How do people and things travel in and through Avon?  Cars  Delivery Trucks  Buses  Bikes  & Internet  Walking/etc.

4 What is a transportation problem in our community?  Truck safety on Avon Mountain is a big problem  “One of the worst traffic accidents in Connecticut history occurred at the intersection of US 44 and Route 10 at the foot of Avon Mountain on July 29, 2005 when a runaway dump truck plowed into many stopped vehicles, causing four deaths.”  “A second crash occurred at the same location on September 7, 2007 when a runaway truck crashed into Nassau's Furniture store. “ * Source: * *

5 Research Question: Will the new Escape Ramp on Avon Mountain work?  A truck ramp was opened in 2008 to prevent further accidents.  This type of truck ramp is called a “Dragnet”.  People when they first see the truck ramp they think the gates look weak and trucks would fall into the restaurant at the end of the “short” truck ramp.

6 How did we do our research?  Looked at truck escape ramp plans with Mr. Whitney, a Civil Engineer  Interviewed Mr. Ferraro, DOT Engineer  Visited the truck ramp on Avon Mountain.  Built a model truck ramp made of lego. We tested many things. Our ideas weren’t all tested (especially not the shock wave).

7 What did we learn about the Avon Mountain Truck Escape Ramp?  Cable nets on dragnet type truck ramps are much stronger than they appear.  The ramp has actually never been tested due to the costs to replace the cable nets, but this type of truck ramp has worked successfully in other places.  The gravel pile was not chosen because due to the area’s climate, the pile would freeze up in the winter.  The ramp even has a deicing system to melt snow and ice build up during the winter.

8 How do Dragnet Type Truck Ramps Work?  Cable nets are connected to steel strips in drums which are set into concrete walls  When a truck hits the cable net, the steel strips are pulled out of the drum like thread on a spool  Pins inside the drums bend the strips as they are pulled out creating friction but still permitting a safe amount of give  This creates a net with a low center of gravity which safely slows the runaway truck without causing the truck to tip

9 Truck Ramp Experiments  Dragnet

10 Other Truck Ramp Experiments for Fun  Marshmallows  Springs and Sponges  Straws

11 What did we conclude?  The dragnet is reliable and it will stop the truck gradually, so the driver and their load will not get damaged.

12 What is a solution to make Avon Mountain even more safe?  Add another dragnet at the other side of the Avon Mountain.

13 How did we communicate that we learned to our community?  We posted our research on the internet at:
